Collaborative Page for the TAP Interface

The Table Access Protocol (TAP) is a second generation DAL interface being developed to provide a general access mechanism for tabular data, including but not limited to astronomical catalogs. TAP is part of the DAL family of data access interfaces.

Work on the TAP VOResource extension schema for registering TAP service is also summarized below.

Scope and Role of the TAP Parameter Query (May 2009)

TAP/Param V0.2 - TAP/Param draft (includes TAP/Param functionality). This is based upon the discussions from the tiger team meeting held at JHU in November 2007 (JHU November 2007), as well as follow-on discussions regarding VOSpace integration, multi-region queries, and other topics.

TAP/QL V0.1 - TAP/QL Draft document focused on processing ADQL queries, synchronous and asynchronous execution, integration with other IVOA services and metadata provision using VOSI constructs.

Registering TAP Services

A VOResource extension schema for registering TAP services is now in development. The current spec only specifies the standardID to use in an otherwise generic <capability> element in the resource record; however, a specialized extension schema will allow for more specific descriptions of how a TAP instance supports the TAP standard; this includes flags that indicate support for ObsCore. Ideas for the needed metadata are being gathered in the TAPRegExt page.
